| 摘 要： | 采用硝酸、高氯酸、氢氟酸处理土壤样品,硝酸为介质用ICP-AES检测或硫酸为介质用API检测,都能够满足全磷含量的检测。并对国家标准物质GBW07403和两种酸介质测定全磷进行验证,测定结果两种酸介质测定全磷含量与标准方法、标准值相吻合,两种处理测定全磷含量的精密度都很高。

| Abstract: | Soil sample s were pretreated by nitric acid,perchloric acid,hydrofluoric acid.The total phosphorus in the samples were determined by ICP-AES in nitric acid,or by API in sulfuric acid.The amounts of total phosphorus detected by the two methods are accord well with national standards material GBW07403 with higher accuracy. |
